Connections is a ten-episode documentary television series and 1978 book ("Connections" based on the series) created, written and presented by science historian James Burke. The series was produced and directed by Mick Jackson of the BBC Science & Features Department and first aired in 1978 (UK) and 1979 (USA). It took an interdisciplinary approach to the history of science and invention and demonstrated how various discoveries, scientific achievements, and historical world events were built from one another successively in an interconnected way to bring about particular aspects of modern technology. The series was noted for Burke's crisp and enthusiastic presentation (and dry humour), historical re-enactments, and intricate working models.

The popular success of the series led to the production of The Day the Universe Changed (1985), a similar program but showing a more linear history of several important scientific developments. Years later the success in syndication led to two sequels, Connections² (1994) and Connections³ (1997), both for TLC. In 2004, KCSM-TV produced a program called Re-Connections, consisting of an interview of Burke and highlights of the original series, for the 25th anniversary of the first broadcast in the USA on PBS.[1]

Modern soldiers demonstrate the use of steel-tipped pikes by the Swiss against Charles the Bold in one of the many re-enactments used in Connections.

Connections explores an "Alternative View of Change" (the subtitle of the series) that rejects the conventional linear and teleological view of historical progress. Burke contends that one cannot consider the development of any particular piece of the modern world in isolation. Rather, the entire gestalt of the modern world is the result of a web of interconnected events, each one consisting of a person or group acting for reasons of their own motivations (e.g., profit, curiosity, religious) with no concept of the final, modern result to which the actions of either them or their contemporaries would lead. The interplay of the results of these isolated events is what drives history and innovation, and is also the main focus of the series and its sequels.

To demonstrate this view, Burke begins each episode with a particular event or innovation in the past (usually Ancient or Medieval times) and traces the path from that event through a series of seemingly unrelated connections to a fundamental and essential aspect of the modern world. For example, the episode "The Long Chain" traces the invention of plastics from the development of the fluyt, a type of Dutch cargo ship.

Burke also explores three corollaries to his initial thesis. The first is that, if history is driven by individuals who act only on what they know at the time, and not because of any idea as to where their actions will eventually lead, then predicting the future course of technological progress is merely conjecture. Therefore, if we are astonished by the connections Burke is able to weave among past events, then we will be equally surprised to what the events of today eventually will lead, especially events we weren't even aware of at the time.

The second and third corollaries are explored most in the introductory and concluding episodes, and they represent the downside of an interconnected history. If history progresses because of the synergistic interaction of past events and innovations, then as history does progress, the number of these events and innovations increases. This increase in possible connections causes the process of innovation to not only continue, but to accelerate. Burke poses the question of what happens when this rate of innovation, or more importantly change itself, becomes too much for the average person to handle, and what this means for individual power, liberty, and privacy.

Lastly, if the entire modern world is built from these interconnected innovations, all increasingly maintained and improved by specialists who required years of training to gain their expertise, what chance does the average citizen without this extensive training have in making an informed decision on practical technological issues, such as the building of nuclear power plants or the funding of controversial projects such as stem cell research? Furthermore, if the modern world is increasingly interconnected, what happens when one of those nodes collapses? Does the entire system follow suit?

The 1978 connected book Connections uses a somewhat different organisation
and different titles for chapters than that of the listed television episodes:

1. "The Trigger Effect"

2. "Death in the Morning"

3. "Distant Voices"

4. "Faith in Numbers"

5. "The Wheel of Fortune"

6. "Fuel to the Flame"

7. "The Long Chain"

8. "Eat, Drink and Be Merry"

9. "Lighting the Way"

10. "Inventing the Future"

i,ii "Further reading" and "Index"

"The Trigger Effect" details the world's present dependence on complex technological networks through a detailed narrative of New York City and the power blackout of 1965. Agricultural technology is traced to its origins in ancient Egypt and the invention of the plough. The segment ends in Kuwait where, because of oil, society leapt from traditional patterns to advanced technology in a period of only about 30 years.

"Distant Voices" suggests that telecommunications exist because Normans had stirrups for horse riding which in turn led them to further advancements in warfare. Deep mine shafts flooded and scientists in search of a solution examined vacuums, air pressure and other natural phenomena.

"The Long Chain" traces the invention of the Fluyt freighter in Holland in the 16th century. Voyages were insured by Edward Lloyd (Lloyd's of London) if the ships' hulls were covered in pitch and tar (which came from the colonies until the American Revolution in 1776). In Culross, Scotland, Archibald Cochrane (9th Earl of Dundonald) tried to distill coal vapour to get coal tar for ships' hulls, which led to the discovery of ammonia. The search for artificial quinine to treat malaria led to the development of artificial dyes, which Germany used to produce fertilizers to grow wheat and led to the advancement of chemistry which in turn led to DuPont's discovery of polymers such as nylon.

"Eat, Drink and Be Merry..." begins with plastic, the plastic credit card and the concept of credit, then leaps back to the time of the Dukes of Burgundy, the first state to use credit. The dukes used credit for many luxuries, and to buy more armour for a stronger army. The Swiss opposed the army of Burgundy and invented a new military formation (with soldiers using pikes) called the Pike Square. The Pike Square, along with events following the French Revolution, set in motion the growth in the size of armies and in the use of ill-trained peasant soldiers. Feeding these large armies became a problem for Napoleon, which caused the innovation of bottled food. The bottled food was first put in champagne bottles then in tin cans. Canned food was used for armies and for navies. In one of the bottles the canned food went bad, and people blamed the spoiled food on "Bad Air", also known as swamp air. Investigations around "bad air" and malaria led to the innovation of air conditioning and refrigeration. In 1892 Sir James Dewar invented a container that could keep liquids hot or cold (the thermos) which led three men – Tsiolkovsky, Robert Goddard, and Hermann Oberth – to construct a large thermal flask for either liquid hydrogen and oxygen or for solid fuel combustion for use in rocket propulsion, applying the thermal flask principle to keep rocket fuel cold and successfully using it for the V-2 rocket and the Saturn V rocket that put man on the moon.

"Countdown" connects the invention of the movie projector to improvements in castle fortifications caused by the invention and use of the cannon. The use of the cannon caused changes in castle fortifications to eliminate a blind spot where cannon fire could not reach. This improvement in castle defence caused innovation in offensive cannon fire, which eventually required maps. Thus a need arose to view and map locations (like a mountain top) from a long distance, which led to the invention of limelight light source, and later the incandescent light. Burke turns to the next ingredient for a movie projector, film. Film is made with celluloid (made with guncotton) which was first invented as a substitute for ivory in billiard balls. Next was the invention of the zoopraxiscope which was first used for a bet to see if a horse's hooves all left the ground at any point while galloping. The zoopraxiscope used frame by frame pictures and holes on the side to allow the machine to pull the film forward. Communication signals for railways using Morse's telegraph led to Edison discovering how to speak into a microphone creating bumps on a disc that could be played back—the record player. This final ingredient gave movies sound. In summary, Burke connects the invention of the movie projector to four major innovations in history: the incandescent light; the discovery of celluloid; the projector that uses frame by frame pictures on celluloid; and finally, recorded sound.

"Yesterday, Tomorrow and You" A recap of the theme that change causes more change. Burke ties together the modern inventions that previous episodes had culminated in: telecommunications, the computer, the jet engine, plastics, rockets, television, the production line, and the atomic bomb. All of these inventions come together in the B-52 nuclear bomber. Start with the plow, you get irrigation, pottery, craftsmen, civilisation and writing, mathematics, a calendar to predict floods, empires, and a modern world where change happens so rapidly you can't keep up. What do you do? Stop the change? Throw away all technology and live like cavemen? Decide what change will be allowed by law? Or just accept that the world is changing faster than we can keep up with?

Routes – Jethro Tull, a sick English lawyer, recuperates sipping wine and contributes the hoe to help fix farming problems. Farm production is not going so well in France, either. François Quesnay (doctor of King Louis XV's mistress) suggests a solution based on his complete misunderstanding of English farming techniques. Laissez-faire was his erroneous idea. It also got the people to demand social laissez-faire. His inciting the public's rebellion against the monarchy led to France's invasion of Geneva. The French Revolution led to personal exploration of the senses. Berlin doctor Müller reasoned that each sense does a different job and the nervous system analyses what the senses are telling you. Helmholtz's pupil, Hertz, discovered that sound and electricity have a wave-like nature in common. Guglielmo Marconi takes this a step further by sending and receiving signals very long distances across the earth. The BBC realised that the radio waves were reflected by the ionosphere, and Hess was the first to suggest that the ionization was due to "Hess rays" later related to solar activity. But World War II started and adding machines were needed to aim artillery and so digital computing was invented. Thus was enabled the GPS which tells you your "Routes."

Feedback – Electronic agents on the internet and wartime guns use feedback techniques discovered in the first place by Claude Bernard, whose vivisection experiments kick off animal rights movements called humane societies that really start out as lifeboat crews rescuing people from all the shipwrecks happening because of all the extra ships out there who are using Matthew Maury's data on wind and currents transmitted by the radio telegraph, invented by Samuel Morse, who's also a painter whose hero is Washington Allston, who spends time in Italy with Samuel Taylor Coleridge, who comes to Malta and spies for the governor Alexander Ball who saved Admiral Horatio Nelson's skin so he can go head over heels for Emma Hamilton in Naples, resulting in an illegitimate son. Emma became notable in the Electrico-Magnetico Celestial Bed, where you go regain your fertility through electricity, and you can get more whiskey thanks to Dr. Joseph Black, who figured the latent heat of vaporisation in steam. James Watt borrowed that information to make a better steam engine. Watt is linked to Roebuck who discovered chlorine bleach which eventually is used to make white paper. The paper is used for decorating walls by William Morris who's a socialist with Annie Besant, who is a vegetarian just like the Seventh-day Adventists. And we end up with W.K. Kellogg's cornflakes.

What's in a Name? – Remember the cornflakes from last episode? Thanks to the fact that corncobs make adhesives to bond Carborundum discovered by Edward Goodrich Acheson, otherwise known as silicon carbide, to grinding wheels used to grind lightbulbs. Silicon carbide is also then used as protection against armour-piercing shells developed to hit tanks that start life as American tractors, which use diesel engines developed thanks to funding from Krupp, who inspired Bismarck's welfare scheme based on Quetelet's statistics that inspired the Charles Babbage's difference engine, whose punch cards were used to rivet the "SS Great Eastern," the monster ship that laid the transatlantic cable insulated with gutta-percha used to manufacture golf balls for factory managers in industrial Scotland, where James Watt had a run-in with Cavendish, whose protegee was James Macie aka James Smithson, who caused all the row in the capitol building, so the money got used to set up a world-renowned institution named after James Macie's new family name, which was Smithson: The institution known as the Smithsonian.

Drop the Apple – At the Smithsonian, we learn of electric crystals that help Pierre and Marie Curie discover what they call radium, and then Langevin uses the piezo-electric crystal to develop sonar that helps save liberty ships (from German U-boats) put together with welding techniques using acetylene made with carbon arcs, also working the arc lights with clockwork regulators built by Foucault, whose pendulum helps him to take pictures of solar eclipses. Also thanks to ash from seaweed, interchangeable parts for clocks, the world of opera, and gurus, we get Einstein's theory of the gravity effect, which means Newton's universe is gone and you can drop the apple.

An Invisible Object – Black holes in space, seen by the Hubble Telescope, brought into space with hydrazine fuel, which was a by-product of fungicidal French vines, fuelled by quarantine conventions and money orders, American Express and Buffalo Bill, Vaudeville and French battles, Joan of Arc and the Inquisition, Jews welcomed by Turks, who lost to Maltese knights with surgeons trained on pictures by Titian, in Augsburg, where goldsmiths made French money to pay for tobacco. That triggered logarithms and slide rules made by clock makers, who also made pressure cookers that sterilised French beer kept cool by refrigerators that were also used to freeze meat and chill down paraffin wax for making objects invisible.

Life is No Picnic – Instant coffee gets off the ground in World War II and Jeeps lead to nylons and stocking machines smashed by Luddites, who were defended by Lord Byron, who meets John Galt in Turkey, avoiding the same blockade that inspires the "Star-Spangled Banner," which was really an English song all about a Greek poet discovered by a publisher whose son-in-law is pals with Joseph Justus Scaliger of chronology fame, whose military boss, Maurice, inspires Gustavus of Sweden, father of the runaway Christina, whose teacher René Descartes' mechanical universe inspires the book about brains by Willis, which is illustrated by the architect of St. Paul's, Christopher Wren, who's dabbles in investments like John Law's Louisiana scam that ruins France, and Pierre Beaumarchais, and later the French finance minister Jacques Necker, whose daughter is the opinionated de Stael, whose romantic pals get Thomas Henry Huxley looking into jellyfish so he can defend Charles Darwin's theory of evolution. This demonstrates that Life is No Picnic.

Elementary Stuff – Alfred Russel Wallace, who studied beetles, Oliver Lodge and telegraphy, a radio designed by Reginald Fessenden, which was used by banana growers, studied by Augustin Pyramus de Candolle, who got the Swiss to use stamps on postcards with cartoons of Gothic Houses of parliament, which in turn had been inspired by Johann Gottfried Herder's Romantic movement, inspired by fake Scottish poems. The exiled Scots escaped to North Carolina, producing turpentine, which helped make Chinese lacquer on tinplate, which is what Jean-Baptiste Colbert had hoped for. French navy decorator Pierre Paul Puget, who paints pictures of locations where barometer are the subject of investigation. The weather experimenter, whose brother's writing turns on Swift, whose pal Berkeley has visual theories that Young confirms while decoding ancient Egyptian from examples sketched by pencils invented by French balloonists. The American balloons are used for spying by Pinkerton and his intrepid agent McParlan, who becomes famous in England because of Conan Doyle.

Hit the Water – Thanks to napalm, made with palm oil, also used for margarine, stiffened with a process using kieselguhr that comes from plankton living in currents studied by Ballot before observing the Doppler Effect that caused Fizeau to measure the speed of light. Fizeau's father-in-law's friend, Prosper Mérimée, who wrote "Carmen"... his friend, Anthony Panizzi, who works at the British Museum, opened to house the collection of Dr. Hans Sloane, who treats Lady Montague's smallpox before she sees Turkish tulips, first drawn by Gesner, whose godfather eats sausages and cancels the military contract with France, which was the first to develop military music and choreography, used in a London show by John Gay, whose friend Arbuthnot does statistics that impress the Dutch mathematician who knows Voltaire, who hears from the worm-slicing Lazzaro Spallanzani, who stars in the story by Judge Hoffman, who tries German nationalists who start gymnastics, adopted by the YMCA and the guy who kicks off the Red Cross, who need a way to figure out blood types, surgical stitching, and the perfusion pump invented by Charles Lindbergh, whose father-in-law's disarmament treaty leads to "Graf Spee," "Altmark, " and the German invasion of Norway and the Allied commandos whose mission was to "Hit the Water."

In Touch – Starting from an attempt for cheaper fusion power using superconductivity, which was discovered by Onnes, with liquid gas provided by Louis-Paul Cailletet, who carried out experiments on a tower built by Gustave Eiffel, who also built the Statue of Liberty with its famous poem by the Jewish activist Emma Lazarus, helped by Oliphant, whose boss Elgin was the son of the man who stole the Elgin Marbles and sold them with the help of royal painter Thomas Lawrence, whose colleague Dr. Hunter had an assistant whose wife's lodger was Benjamin Franklin, who charted the Gulf Stream with a thermometer Fahrenheit borrowed from Ole Rømer, whose friend Picard surveyed Versailles and provided the water for the fountains and the royal gardens and all the trees that inspired Duhamel to write the book on gardening that was read by the architect William Chambers, who hired the Scottish stonemason Thomas Telford, whose idea for London Bridge was turned down by Thomas Young, whose light waves travel in ether, as do Hertz's electricity waves, with which Helmholtz prods a frog to disprove the vitalists, whose leader, Klages, analyses handwriting so individual zip codes have to be capital letters to get your mail to a jungle village to keep you "In Touch".

All three Connections documentaries have been released in their entirety as DVD box sets in the US (Region 1) only.

Burke also wrote a series of Connections articles in Scientific American, and published a book of the same name (1995, ISBN 0-316-11672-6), all built on the same theme of exploring the history of science and ideas, going back and forth through time explaining things on the way and, generally, coming back to the starting point.

Connections, a Myst-style computer game with James Burke and others providing video footage and voice acting, was released in 1995.[2]

Burke produced another documentary series called The Day the Universe Changed in 1985, which explored man's concept of how the universe worked in a manner similar to the original Connections.
